NOTE: After applying this patch(es), the following standard spkg can be
completely deleted:
ghmm-20080813.p0.spkg
This patch provides a complete reimplementation of Hidden Markov Models
from scratch in Sage. It is now doctested and the tests should pass on
all standard Sage platforms. Note that that HMM code in sage-4.3.4 and
earlier is *NOT* tested at all, can easily segfault in all kinds of cases,
leaks huge amounts of memory, etc. The new code shouldn't have those
defects. Plus we get to delete a standard spkg. Moreover, this new code
is much easier to modify and experiment with. Performance is generally
similar, sometimes better, and sometimes worse, than the old code.
